Subarachnoid Hemorrhage
When dealing with Subarachnoid Hemorrhage, a type of stroke caused by bleeding into the space between the brain and its surrounding membrane. Also known as SAH, it demands fast action because blood in that delicate area can raise pressure, choke the brain, and trigger a cascade of complications.
Subarachnoid hemorrhage most often follows a ruptured aneurysm, a weakened bulge in a blood vessel wall. The rupture creates a sudden gush of blood, which then spreads through the cerebrospinal fluid. This event encompasses a cascade: increased intracranial pressure, reduced oxygen delivery, and a risk of vasospasm that can further starve brain tissue. Early identification hinges on a quick CT scan—the go‑to imaging test that spots fresh blood within minutes. If the CT is inconclusive but suspicion stays high, a lumbar puncture or an MRI can confirm the bleed. The condition requires coordinated neurocritical care to manage blood pressure, prevent re‑bleeding, and treat potential complications like hydrocephalus.
What you’ll see in the article list below reflects the breadth of this topic. We cover the anatomy of the subarachnoid space, the warning signs that differentiate SAH from a migraine, and the latest endovascular techniques to secure a ruptured aneurysm. There are guides on medication choices for vasospasm, lifestyle tweaks that lower aneurysm risk, and practical tips for families navigating emergency care. Whether you’re a patient, a caregiver, or a health‑professor looking for quick references, the collection gives you a clear roadmap from symptom onset to long‑term recovery.
